A HelmetMountedSight is essentially a [[{{HUD}} Heads Up Display]] that tells your [[CoolPlane fighter]]/chopper where you want the [[MoreDakka bullets]] or [[MacrossMissileMassacre missiles]] to go. It also can show what friendly or enemy fighters are equipped with to provide StatOVision. This can appear in modern or sci-fi settings, but [[ElitesAreMoreGlamorous only the most elite]] soldiers or [[OneManArmy very powerful single]] combatants are likely to have it equipped.

This trope is becoming more Defictionalized as time goes on.

!!Examples:

[[foldercontrol]]

[[folder:{{Anime}}]]
* The prototype [=VF-0=] ''[[TransformingMecha Valkyrie]]'' in ''MacrossZero'' does it one better: the helmet tracks the pilot's ''eyeballs'' in order to acquire targets for the mecha's head-mounted cannons. Presumably, this became a standard feature, but this is one of only two times we actually see how it works.
** The other time it appears on screen is a blink and you'll miss it moment with Ozma in {{Macross Frontier}}.
* The [[HumongousMecha Arm Slaves]] in ''LightNovel/FullMetalPanic'' have the pilot wear a special headband over their forehead so the cockpit can track their head motions. This in turn allows the pilot to control the facing of the Arm Slave's head by moving their own. Since many models of Arm Slave mount machine guns in their head, this allows the pilot to direct point defense literally at a glance.

[[folder:Comics]]
* ComicBook/{{Deadshot}}, a Franchise/{{Batman}} villain and a member of the Comicbook/SuicideSquad and the SecretSix has one of these.
[[/folder]]

[[folder:Film]]
* ''Film/{{Predator}}''. The title creature's shoulder cannon moves in synch with its helmet.
** In ''AliensVsPredatorRequiem'', the Predator installs a second plasmacaster on the other shoulder, although both are controlled by the same sight.
* ''Film/BlueThunder''. The direction of the title helicopter's autocannon is controlled by its pilot's helmet.
* Nicholas Cage's character in ''Film/FireBirds'', a rookie Apache pilot, has trouble learning to use one of these, leading to some... ''innovative'' teaching methods on the part of his instructor.
* In ''Film/HalfPastDead'', StevenSeagal's character explains to his friend (played by JaRule) how to operate a crashed helicopter's gun using the helmet. When the firefight breaks out, it comes in handy.

[[folder:Live Action TV]]
* ''Series/{{Airwolf}}'' has one in Stringfellow Hawke's helmet.

[[folder:VideoGames]]
* There was a third-party product for the NES which was a headset-mounted zapper gun.

[[folder:Virtual Reality Games]]
* A VR game like this was at Segaworld in London's Trocadero c. 1999.

[[folder:Real Life]]
* [[http://tri.army.mil/LC/cs/csa/apihadss.htm US helicopter gunships since the early 1980s have used the IHADSS system]], which can not only aim a laser designator for [[AirLaunchedWeapons the AGM114 laser-guided antitank missile]], but also aim an autocannon in the powered turret under the helicopter's "chin"
* The first widespread implementation in a fighter aircraft was the [=MiG-29=] "Fulcrum" in the 1980's, causing some alarm within NATO after they discovered how effective they were from ex-[[EastGermany GDR]] examples of that plane, particularly in combination with the R-73/AA-11 heat-seeking missile. The US Air Force and Navy, who had been rolling them out rather tentatively until this point, were quick to catch up.
* The F22 and F35 are/will be equipped with these. Several attack helicopters are equipped with them as well.
** Specifically these aircraft, along with several older U.S. fighters like the F-15, F-16, and F/A-18 will be made compatible with the new Joint Helmet-Mounted Cueing System, which when combined with the new AIM-9X model of the Sidewinder allows for some absolutely gratuitous stunts involving {{Roboteching}}.
